Distance = speed x time
speed = distance/time
time = distance / speed
400m/36s = 11 1/9 m per second
when dividing two fractions ex:
(1/3) / (1/6)
we take the reciprocal (we switch the bottom and top numbers) of the second fraction and then change the division into multiplication
(1/3) x (6/1)
multiply across to get
6/3
which is 2
hope this helps
